The best thing of stir-fry is quick and easy. Made this dish because I had a bag of frozen Chinese veggies in the freezer, it's a mixture of carrot strips, red bell pepper strips, snow peas, baby corn and water chestnuts. I also added a cup of frozen broccoli that's not from the mix. Of course you can always use fresh and similar texture veggies. Miso or soy bean paste, Korean chili paste can be found in Asian grocery stores, or just use soy sauce, some hot sauce instead, it will be still tasty.
